For crash reduction, I don't think it does anything that llvm-reduce
can't. Pass pipeline reduction also has a separate reduction script.
The main thing there isn't a replacement tool is the miscompilation
reducer, but I'm not sure that's actually functioned for years.
There are still some references to bugpoint in various comments
and pieces of documentation that don't all necessarily make sense
to replace or remove. In particular there are a few passes documented
as "only for bugpoint", but I've left those alone in case they are
useful for manual reductions.
